Things post is sponsored by Lego Friends Lego would have to be the most used toy in our home, so much so that a few years ago we made my son a Lego Storage Unit in his bedroom dedicated to displaying his creations!
All you need is some LEGO and a little inspiration to build your own LEGO dollhouse. House instructions are available online for purchase and for free. Plenty of LEGO dollhouse sets are available and you can buy multiples of one set and mix with.
Lovely detailing on this cake. It would be fairly time consuming but would be great fun. I can make something like this for if you provide the characters or I could do some of the Lego characters in sugarpaste for each.
